WebOver the last decade optimization techniques have been studied for application to the rotor blade design process. In Ref. 1 Miura presents a survey on the application of nu-merical optimization methods to helicopter design prob-lems including rotor blade design. Most optimization pro-cedures have dealt with a single discipline such as aerody- WebDynamic Optimization Joshua Wilde, revised by Isabel ecu,T akTeshi Suzuki and María José Boccardi August 13, 2013 Up to this point, we have only considered constrained optimization problems at a single point in time. However, many constrained optimization problems in economics deal not only with the present, but with future time periods as well.
WebAn integrated aerodynamic/dynamic optimization procedure is used to minimize blade weight and 4 per rev vertical hub shear for a rotor blade in forward flight. The coupling of aerodynamics and dynamics is accomplished through the inclusion of airloads which vary with the design variables during the optimization process.
